Alan, Pavel and other people are suggesting pragmatic *long-term* solutions,
like moving kernel.org outside problematic geopolitical area.  Tainting *our*
code-base with (confusing for *our* users) workarounds doesn't belong in this
class of solutions.. actually no.. it is a PURE F*CKING IDIOCY..

Microsoft having patents on their *obsolete* filesystem should be *their*
problem, not *ours*.  We keep said filesystem strictly for compatibility
reasons and not because we would like to encourage hardware/software vendors
or users to use it.  Lets just update VFAT help text to mention potential
risks of using it, default it to N, rip it from defconfigs, pass it through
lawyers, remove CONFIG_VFAT_FS_DUALNAMES and move on..

When it comes to distributions if they really need they can easily deal with
the problem by simply allowing the 3-rd parties to host the repositories with
risky package (like they do with mp3 etc).

The end result is that end-users can still use full vfat, vendors are safe,
kernel developers don't waste their time on artificial problems and the blame
goes where it belong..

[ The validity of potentially bogus patents (or problems of hardware vendors
  caused by *their* decisions to use *obsolete* and patent-risky filesystem in
  their products) is an entirely different matter/discussion and it shouldn't
  be mixed with technical solutions.. ]
